A beautiful video, once again, from Michael Stevens, titled “How Earth Moves”. Michael explains many concepts, including “sub-solar point”, “sidereal day vs solar day”, or “how Earth moves in the space” etc, and he is doing it in a very simplified manner. Enjoy!Continue reading How Earth Moves (Video)→

Earth is a blue marble in the space: the water, gives our planet its blue color: about 71 percent of the Earth’s surface is water-covered. There is roughly 326 million cubic miles (1.332 billion cubic kilometers) water on the Earth’s surface. Almost 97% of that water is salty (ocean water). But where all that water came from?Continue reading Where Earth’s water came from?→

We evolved here on Earth, and for thousands of years, we just thought the Earth is also the universe, or at least the most important and the biggest part of it. Our brains, our minds, has been adapted the life on Earth and the basic survival needs. So we can deal with the moderate sized objects which have moderate velocity, we can understand the small numbers like 1, 2, 50, we can conceptualize the small distances like two kilometer, or the distance from our “cave” to the nearest river. But when the numbers and distances get bigger, I mean much bigger, like the distance from Earth to the Sun, it become incredibly difficult to conceptualize.Continue reading A Scale Model of Solar System Drawn in the Desert and the Result is Stunning→

In January 2015, Caltech (California Institute of Technology) astronomers Konstantin Batygin and Michael E. Brown published an article titled Evidence For A Distant Giant Planet In The Solar System, and announced calculation-based evidence of a massive ninth planet. Despite they have had started their research to demonstrate that there’s no ninth planet, they reached the exact opposite result: there must be a ninth planet beyond Pluto, and it’s probably 10 times the mass of Earth (for comparison, Neptune has 17 times as much mass compared to the Earth).Continue reading Planet Nine – Where is it?→
